===IQ testing===
Terman published the ''Stanford Revision of the [[Binet-Simon Intelligence Test]]'' in 1916 and revisions were released in 1937 and 1960.<ref>{{cite web|url=http://www.infoplease.com/ce6/people/A0848220.html|title=Terman, Lewis Madison - Infoplease.com|access-date=8 October 2014}}</ref> Original work on the test had been completed by [[Alfred Binet]] and [[Théodore Simon]] of France. Terman promoted his test – the "Stanford-Binet" – as an aid for the classification of developmentally disabled children. Early on, Terman adopted [[William Stern (psychologist)|William Stern]]'s suggestion that ''mental age/chronological age times 100'' be made the ''[[intelligence quotient]]'' or ''IQ''. Later revisions adopted [[David Wechsler|David Wechsler's]] cohort-norming of IQ.

Revisions (mostly recently the fifth) of the Stanford-Binet remain in widespread use as a measure of [[general intelligence]] for both adults and for children.

The first mass administration of IQ testing was done with 1.7 million soldiers during [[World War I]], when Terman served in a psychological testing role with the United States military. Terman was able to work with other applied psychologists to categorize army recruits. The recruits were given group intelligence tests which took about an hour to administer. Testing options included [[Army Alpha]], a text-based test, and [[Army Beta]], a picture-based test for nonreaders. 25% could not complete the Alpha test.<ref>Teigen, En psykologihistorie, page 235</ref> The examiners scored the tests on a scale ranging from "A" through "E".

Recruits who earned scores of "A" would be trained as officers while those who earned scores of "D" and "E" would never receive officer training. The work of psychologists during the war proved to Americans that intelligence tests could have broader utility. After the war Terman and his colleagues pressed for intelligence tests to be used in schools to improve the efficiency of growing American schools.
